Does this mean that games cant be moddable?

Well, the solution to was just resolved. Thanks to @ Sweeney now the engine is free, which means modders will have access to the editor to make mods and levels and such.

Now our job as game makers will be to figure out what and how to provide modders with just enough stuff to mod, without giving away the whole game. Any thoughts on ?

I am thinking some sort of ‘base pack’ if you want to give them access to static models and such for mapping. As for modding, perhaps your game will need a ‘hook’ that looks in a new directory for new gamemodes, new characters, etc…
